Packets of the dipping sauce will be available at 2 p.m. Oct. 7 at select McDonald's restaurants across the nation, including one restaurant in central Pennsylvania. Find it at the McDonald's at 333 E. King St. in Shippensburg.

The savory and slightly sweet sauce, with hints of soy, ginger, garlic, and slight vinegar notes, will be available at the restaurant along with a chance to receive a limited-edition sauce poster.

The posters were announced last week in tandem with the release of McDonald's new Buttermilk Crispy Tenders. The nine gig-style posters were designed by artists from Delicious Design League.

The posters will be available at the Shippensburg restaurant. Also, McDonald's restaurants in Lancaster County at 210 W. King St. and 1295 Millersville Pike will have the posters but no sauce. Purchase of Buttermilk Crispy Tenders is required to be eligible for the poster giveaway.

The Szechuan Sauce has regained popularity thanks to the Adult Swim cartoon, "Rick and Morty." It was originally released as part of a promotion connected to the Disney movie "Mulan."
